Embodiment 1

[0025] This embodiment includes the following steps:

[0026] (1) Enzymatic hydrolysis: 100 kg of Citrus aurantium (10.50% hesperidin content, 8.31% neohesperidin content, 6.23% naringin content, and 1.55% synephrine content) are crushed, infiltrated with 350kg water, and 0.35kg is added. Pectinase, enzymatic hydrolysis for 24 hours; (2) Extraction: add 2800kg of water to the enzymatically hydrolyzed raw materials, extract at 80°C for 2.5 hours, filter and cool to obtain a water extract, and water extract residue for use; (3) membrane separation : Filter the water extract with a nanofiltration membrane with a molecular weight cut-off of 800 to obtain the permeate and the retentate; (4) Separation of synephrine: absorb the permeate of the nanofiltration membrane with an anionic resin, and use a 2.5bv concentration as 1% ammonia is hydrolyzed and absorbed, concentrated, and recrystallized with dichloromethane to obtain synephrine 1.39kg, purity 98.77wt%, yield 89.68%; (5) Separatio...

Embodiment 2

[0028] This embodiment includes the following steps:

[0029] (1) Enzymatic hydrolysis: 100 kg of Citrus aurantium (10.50% hesperidin content, 8.31% neohesperidin content, 6.23% naringin content, and 1.55% synephrine content) are crushed, infiltrated with 400 kg of water, and 0.2 kg is added Pectinase, enzymatic hydrolysis for 20 hours; (2) Extraction: add 2500kg of water to the raw materials after enzymatic hydrolysis, extract for 2 hours at 70°C, filter and cool to obtain water extract, water extract residue for later use; (3) membrane separation : Filter the water extract with a nanofiltration membrane with a molecular weight cut-off of 600 to obtain a permeate and a retentate; (4) Separation of synephrine: absorb the permeate from the nanofiltration membrane with an anionic resin and use 2bv with a concentration of 1.5 % Ammonia is hydrolyzed and absorbed, concentrated, and refined by recrystallization of petroleum ether to obtain synephrine 1.3kg, purity 98.65wt%, yield 83.8...

Abstract

The invention discloses a method for separating high-purity hesperidin, neohesperidin, naringin and synephrine from fructus aurantii Immaturus, and relates to a method for extraction of effective components of traditional Chinese medicines. The method includes the following steps: (1) enzymolysis, (2) extraction, (3) membrane separation, (4) synephrine separation, (5) naringin separation, (6) neohesperidin separation, and (7) hesperidin separation. The method has the advantages that the method overcomes the shortcomings in prior art, provides a new effective method which is easy to industrially produce, and is capable of combined extraction and separation various effective components in the fructus aurantii Immaturus, the method has the advantages of simple operation, high extraction rate, and high purity of the effective components, and the effective components all are separated, and easy to use.

Description

Technical field [0001] The present invention relates to a method for extracting effective ingredients of traditional Chinese medicine, in particular to a method capable of jointly extracting and separating multiple effective ingredients from Fructus Aurantii. Background technique [0002] Citrus aurantium is the dried young fruit of the Rutaceae plant Lime and its cultivars or sweet orange. Traditional Chinese medicine is used to treat stagnation and internal stagnation, fullness of swelling and pain, heavy diarrhea, obstruction of stool, phlegm stagnation and air blockage, chest pain, Chest, drooping organs. The effective ingredients of Fructus Aurantii include volatile oil, alkaloids and various glycosides. The main components of volatile oil are d-limonene and dextro-linalool; the main components of alkaloids are synephrine and N-methyltyramine; the glycosides are mainly hesperidin, neohesperidin, naringin, wild Anacardin, honeysuckle, etc. The various effective ingredients...
